BS3087:1959 will then be superseded and withdrawn. A British Standard does not purport to include all the necessary provisions of a cont

8、ract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

This will be indicated in the amendment table on the inside front cover.BS3087-1:1991 BSI 09-1999 1 1 Scope This Part of BS3087 gives an index and general introduction to the Parts of thi

10、s British Standard for pliers, pincers and nippers. NOTEThe titles of the publications referred to in this standard are listed on the inside back cover. 2 General 2.1 Objects of the standard This standard presents a simplified range of types and sizes of pliers, pincers and nippers which should be s

11、uitable for most everyday applications. A minimum standard of quality of the tools is ensured so that they will have a useful life. 2.2 Quality considerations The duties required of a pair of pliers, pincers or nippers are often severe. There are, for example, many fields in which it is necessary fo

12、r them to be able to cut hard steel wire, soft copper wire and cotton with equal facility. Many experiments and developments are currently taking place on the material for, and heat-treatment of, these tools and so the quality of the tools is ensured by stringent performance tests. These test requir

13、ements have been designed to simulate the function of the tool in normal average use. 2.3 Insulated pliers and nippers used for live circuit working The general requirements for insulated pliers, used for live circuit working, are given in IEC900. Reference should also be made to the Electricity Sup

14、ply Industry (ESI) standard26-3, “Hand held insulated tools for live working up to1000 volts”. 1) NOTEIt is now common practice to supply pliers fitted with plastics sleeving. It should not be assumed that these pliers provide any measure of protection for live circuit working. 3 List of Parts This

15、British Standard closely follows, but is not always technically equivalent to, standards adopted by the International Organization for Standardization (ISO). It is divided into the following Parts. Part1: General introduction; Part2: Nomenclature (see ISO5742); Part3: Specification for general requi

16、rements (see ISO5743); Part4: Methods of test (technically equivalent to ISO5744); Part5: Specification for dimensions of pliers for gripping and manipulating (see ISO5745); Part6: Specification for dimensions of engineers and linemans pliers (see ISO5746); Part7: Specification for dimensions of lev

17、er assisted side cutting pliers, end and diagonal cutting nippers (see ISO5747); Part8: Specification for dimensions of end cutting nippers (see ISO5748); Part9: Specification for dimensions of diagonal cutting nippers (see ISO5749); Part10: Specification for dimensions of tools not standardized by

18、ISO; Part11: Specification for dimensions and test values of slip joint pliers (see ISO9343); Part12: Specification for dimensions and test values of construction workers pincers (seeISO9242); Part13: Specification for dimensions and test values of carpenters pincers (see ISO9243); Part14: Specifica

19、tion for dimensions and test values of multiple slip joint pliers (see ISO8976).
